The present invention relates to a cumulatively dyeing hair dye which does not require washing of hair immediately after used and by which the hair are gradually dyed every time using it reaptedly. More specifically, it relates to a hair dye which is excellent in water resistance and which is excellent as well in a cumulative hair dyeing property and usability and an applicator for hair using the above hair dye.
Permanent hair dyes (oxidizing hair dyes) and semi-permanent hair dyes (acid hair dyes) which have so far usually been used have such large defects that dyeing operation in use is complicated and troublesome and that the circumference, cloths and the skin of users are dyed.
Accordingly, they have to be applied usually in beauty solons or they have to be applied by ourselves in bathing so that they can be washed away soon even if stained, and therefore an excessive burden has been forced to the users.
A cumulatively dyeing temporary hair dye (refer to patent document 1) provided by the present applicant which comprises 0.01 to 3% by weight of an acid dye as a coloring agent, 1.5 to 10% by weight of a nonionic or anionic silicone base resin, 3 to 20% by weight of a hair dyeing auxiliary, 30 to 80% by weight of a lower alcohol and 5 to 50% by weight of water and which has a pH of 2 to 5 and a viscosity of 100 mPa·s or less is known as a hair dye which can reduce the above burden and which can cumulatively dye hair by using repeatedly with simplicity even if a dyeing amount per once is small.
Further, known are an acid hair dye composition (patent document 2) prepared by blending 0.01 to 1% of at least one of acid dyes, 0.1 to 10% of an acid as a pH controlling agent, 1 to 20% of an aromatic alcohol as a penetrant, 1 to 20% of a lower alcohol as a solvent and 0.01 to 5% of a polymer compound as a thickener and an acid hair dye composition (patent document 3) prepared by blending 0.01 to 10.0% of at least one of amino-modified or ammonium-modified polymer silicones represented by a specific formula.
The hair dye described in patent document 1 is excellent as a hair dye which can cumulatively dye hair, but it is a little inferior in water resistance. Also, the acid hair dye compositions described in patent documents 2 and 3 described above are common in terms of using acid dyes, but they involve problems in terms of being inferior in water resistance and a hair dyeing property. Further, they have a high viscosity and therefore have such a problem in terms of usability that they are not unsuited to use with an applicator for hair having an occlusion body such as a sliver and the like.
In light of the problems of the conventional art described above, the present invention intends to solve them, and an object thereof is to provide a hair dye which is excellent in water resistance and usability and which is excellent as well in a cumulative hair dyeing property and an applicator for hair using the above hair dye.
Intensive studies repeated by the present inventors on the problems of the conventional art described above have resulted in finding that a hair dye meeting the object described above and an applicator for hair using the hair dye are obtained by using an aqueous acid dye, a resin comprising a specific terpolymer, a hair dyeing auxiliary agent, a lower alcohol and water and controlling the contents thereof respectively in specific ranges, and thus the present invention has come to be completed.
That is, the present invention comprises the following items (1) to (9).

The specific examples of the aqueous acid dye involves at least one (alone or a mixture of two or more kinds thereof; hereinafter the same shall apply) of Red No. 3 (Erythrosine), Red No. 102 (New Coccine), Red No. 207 (Lithol Red BA), Orange No. 205 (Orange II), Yellow No. 4 (Tartrazine), Yellow No. 402 (Polar Yellow 5G), Yellow No. 403 (1) (Naphthol Yellow S), Green No. 3 (Fast Green FCF), Green No. 204 (Pyranine Conc.), Blue No. 1 (Brilliant Blue FCF), Blue No. 202 (Patent Blue NA), Purple No. 401 (Arizurol Purple), Brown No. 201 (Resorcin Brown), Black No. 401 (Naphthol Blue Black), but they shall not be restricted to the above compounds.
A content of the above aqueous acid dyes has to be 0.1 to 3.0% by weight (hereinafter referred to merely as “%”) based on the total amount of the hair dye, and it is preferably 0.1 to 1%.
If a content of the aqueous acid dye is less than 0.1%, the hair dyeing effect is not sufficiently exerted, and if it exceeds 3%, stain toward the other parts such as the skin is liable to be caused. Accordingly, both are not preferred.
The resin (hereinafter referred to merely as “the terpolymer”) comprising a terpolymer used in the present invention is a resin which is suited for allowing the water resistance to be consistent with the cumulative hair dyeing property to a high degree and reducing a viscosity of the hair dye, and it is the resin comprising the terpolymer constituted from a vinyl cyclic amide represented by Formula (I), an acrylic acid derivative represented by Formula (II) and a quaternary derivative of acrylic acid represented by Formula (III).
The resin comprising the terpolymer constituted from 40 to 95% of the vinyl cyclic amide represented by Formula (I), 0.1 to 55% of the acrylic acid derivative represented by Formula (II) and 0.25 to 50% of the quaternary derivative of acrylic acid represented by Formula (III) is preferably used from the viewpoints of water solubility and water resistance after drying, and the resin comprising the ternary polymer constituted from 60 to 90% of the vinyl cyclic amide represented by Formula (I), 5 to 30% of the acrylic acid derivative represented by Formula (II) and 1 to 30% of the quaternary derivative of acrylic acid represented by Formula (III) is more preferably used.
The terpolymer used in the present invention is a cationic polymer which is modified so that it is hydrophobic, and it has long chain alkyl therein. The typical terpolymer is constituted from vinyl pyrrolidone represented by Formula (I), dimethylaminopropylacrylamide (DMAPAA) represented by Formula (II) and an alkyl quaternary derivative of DMAPAA represented by Formula (III) in which the alkyl has 12 to 18 carbon atoms, more preferably 12 carbon atoms, wherein a content of the compound represented by Formula (I) is 60 to 90%; that of the compound represented by Formula (II) is 5 to 30%; and that of the compound represented by Formula (III) is 1 to 30%. It is, for example, a polymer represented by the following formula:
##STR00007##
Alkyldimethylaminopropylacrylamide which is the compound represented by Formula (III) described above is preferably prepared by tosylating DMAPAA as shown below:
##STR00008##
The terpolymer used in the present invention is preferably a terpolymer which has a weight average molecular weight of 200,000 to 2,000,000, preferably 400,000 to 800,000 and is water-soluble or water-dispersible and which forms, when cast on a surface of a support, an apparently moisture resistant and hydrophobic film, wherein the film is surface-active and stable against hydrolysis, and the terpolymer is more preferably homogeneous.
The usable commercial products of the terpolymer involve STYLEZE W-10 (obtained by controlling Polyquaternium 55 (manufactured by ISP Ltd.) to a resin solid content of 10%), STYLEZE W-20 (obtained by controlling Polyquaternium 55 (manufactured by ISP Ltd.) to a resin solid content of 20%) and the like.
The above terpolymers have to be controlled to 0.1 to 2.5% in terms of a solid content, preferably 0.1 to 1.5% and more preferably 0.3 to 1.0% based on the total amount of the hair dye.
If a content of the terpolymer is less than 0.1%, the sufficiently high water resistance is not attained. On the other hand, if it exceeds 2.5%, the cumulative hair dyeing property is reduced, and a viscosity of the liquid is too high, so that it is less liable to be handled.
The hair dyeing auxiliary agent used in the present invention is added in order to exhibit more hair dyeing effect and includes, for example, at least one selected from monohydric alcohols, polyhydric alcohols, ether alcohol, lower alkylene carbonates, N-alkylpyrrolidones and lactones.
To be specific, monohydric alcohols which are not involved in the lower alcohols described above as the hair dye component can be used as the monohydric alcohol, and it involves benzyl alcohol, phenethyl alcohol, furfuryl alcohol, cyclohexanol and the like. The polyhydric alcohol involves ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin, diglycerin, dipropylene glycol and the like. The ether alcohol involves methyl cellosolve, ethyl cellosolve, butyl cellosolve, methyl carbitol, ethyl carbitol, propyl carbitol, butyl carbitol and the like. The lower alkylene carbonate involves ethylene carbonate, propylene carbonate, butylene carbonate and the like. The N-alkylpyrrolidones (lactams) involve N-methylpyrrolidone (N-methyl-2-pyrrolidone), N-ethylpyrrolidone, N-octylpyrrolidone and the like. The lactones involve γ-butyrolactone and the like. They can be used alone or in a mixture of two or more kinds thereof.
Benzyl alcohol, N-methylpyrrolidone (N-methyl-2-pyrrolidone), propylene carbonate and the like are preferred in terms of safety, a drying property and an odor.
A content of the above hair dyeing auxiliary agents is preferably 1 to 20%, more preferably 5 to 15% based on the total amount of the hair dye.
If a content of the hair dyeing auxiliary agent is less than 1%, the hair dyeing effect is not sufficiently exerted. On the other hand, if it exceeds 20%, the drying property after applying is reduced. Accordingly, both are not preferred.
At least one of lower alcohols which can be used for hair dyes, such as ethanol, propanol, butanol, isopropanol, isobutanol and the like can be used as the lower alcohol for the present invention, and ethanol is preferably used in terms of safety, a drying property and an odor.
A content of the lower alcohol described above has to be 20 to 60% based on the total amount of the hair dye, and it is preferably 20 to 45%.
If a content of the lower alcohol is less than 20%, the drying property is reduced, and if it exceeds 60%, the hair dyeing effect is not sufficiently exerted. Accordingly, both are not preferred.
The balance of the hair dye in the present invention is controlled by water, and refined water, distilled water, ion-exchanged water, purified water, ultrapure water, clean water, aqua and the like can be used. A content thereof has to be 20 to 60% based on the total amount of the hair dye, and it is preferably 35 to 60%.
If a content of water is less than 20%, the hair dyeing effect is reduced, and if it exceeds 60%, the drying property and the low temperature stability are reduced. Accordingly, both are not preferred.
Other optional components can suitably be added to the hair dye of the present invention as long as the effects of the present invention and stability of the system are not damaged, and capable of being added are, for example, various surfactants, antiseptic agents, antioxidants, reduction inhibitors, chelating agents, UV absorbers, viscosity controlling agents, oil components, silicone derivatives, pigments, fragrances, animal and plant extracts, well-known polymer components and the like.
In the hair dye of the present invention, the aqueous acid dye and the resin comprising the terpolymer described above are factors exerting an effect on the hair dyeing property and the water resistance, and they are added in the ranges of the respective contents described above. From the viewpoint of improving further more the hair dyeing property and the water resistance, the following Formula (IV) is more preferably satisfied assuming that a content ratio of the aqueous acid dye is y (% by weight) and that a solid content of the resin comprising the terpolymer described above is x (% by weight):
0.1(x+1)<y≦0.264x+0.4 (IV)
For example, when a content of the aqueous acid dye is 0.5% by weight, a solid content x of the resin used is preferably 0.379 (≈0.3787878 . . . ) % by weight or more (to 2.5% by weight).
Further, in the hair dye of the present invention, water and the lower alcohol are factors exerting an effect on stability and a hair dyeing property of the resin comprising the terpolymer dissolved in the hair dye, and they are added in the ranges of the respective contents described above. From the viewpoint of improving further more the stability and the hair dyeing property, a content ratio (A)/[(A)+(B)] of water (A) to the lower alcohol (B) is preferably 0.3 to 0.8 in terms of a weight ratio.
In the hair dye of the present invention, pH is set to 2 to 4 from the viewpoints of using the aqueous acid dye and preventing hair damage and skin irritation.
If a pH of the hair dye exceeds 4, the hair dyeing property is unsatisfactory, and therefore it is not preferred. On the other hand, if the pH is less than 2, irritation to the skin and damage to the hair are brought about in a certain case, and therefore it is not preferred.
In the present invention, the pH can be controlled by optionally using conventional pH controlling agents, for example, organic and inorganic bases such as triethanolamine, potassium hydroxide, sodium hydroxide and the like and organic and inorganic acids such as citric acid, malic acid, hydrochloric acid, glycolic acid and the like.
A viscosity of the hair dye of the present invention is 2 to 50 mPa·s, preferably 3 to 30 mPa·s from the viewpoint of readily applying it onto hair.
If a viscosity of the hair dye is less than 2 mPa·s, it is liable to be adhered onto the scalp, and it is liable to be spattered to stain the cloth. On the other hand, if it exceeds 50 mPa·s, it is difficult to spread the hair dye thinly and evenly on the hair. Accordingly both are not preferred.
The hair dye in the present invention can be produced by blending the respective components such as the aqueous acid dye, the terpolymer, the hair dyeing auxiliary agent, the lower alcohol, water and the like each described above in the ranges of the respective contents described above and evenly stirring and mixing them.
The hair dye of the present invention thus constituted can suitably be used as a hair color for black hair, a hair color for gray hair and the like, and obtained is the hair dye which does not dye the skin and is excellent in a cumulative dyeing property and which has excellent water resistance against sweat, rain and the like in a hot humid season such as a summertime and is excellent in usability. In particular, it functions as a primary coloring agent which does not cause skin irritation even when applied on the hair in a wide range and is excellent in a drying property and which can be used over an extended period of time after dried and can sufficiently endure rain and sweat. Further, it is endowed with such an excellent cumulative hair dyeing property and usability that the color remains on the hair even after washing the hair and that the hair are gradually dyed by repeatedly using the hair dye.
An applicator for hair is used in using the hair dye of the present invention thus constituted, and the applicator for hair used shall not specifically be restricted in a form, a structure and the like.
In the present invention, the applicator for hair which can be used involves preferably, from the viewpoints of applying on the hair, controlling a liquid amount supplied to the applying part, less stain caused on cloths, skins, furniture and the like and usability, an applicator for hair having a storing part for storing the hair dye of the present invention, and involves more preferably an applicator for hair in which an applying main body part comprising an applying body for applying a hair dye on hair and a comb part disposed on a periphery of the applying body is mounted at a tip part of the applicator main body.

As apparent from the results shown in Tables 1 to 3 described above, it has found that the hair dyes prepared in Examples 1 to 23 each falling in the scope of the present invention are excellent, as compared with the hair dyes prepared in Comparative Examples 1 to 12 each falling outside the scope of the present invention, in water resistance, a cumulative hair dyeing property (5 times), an applying performance, low temperature stability and a drying property and that they are free from skin irritation.
To observe individually the comparative examples, resins other than the resin comprising the terpolymer are used in Comparative Examples 1 and 2. That is, MERQUAT 280 (NALCO Company; Polyquaternium-22, resin solid content: 40%, acrylic acid: 20%, diallyldimethylamonium chloride: 80%) was used in Comparative Example 1, and in this case, the hair dye is inferior in water resistance and somewhat inferior as well in a cumulative hair dyeing property. Comparative Example 2 is a case in which CELQUAT SC240C (National Starch & Chemical Company; Polyquaternium-10, powder, Polyquaternium-10, cationic hydroxycellulose) was used, and in this case, it can be found that the hair dye is a little inferior as well in water resistance and inferior in a cumulative hair dyeing property and an applying performance.
Further, it can be found that settling is caused in Comparative Examples 3 and 9 in which a content of water is large and that the effects of the present invention (water resistance, cumulative hair dyeing property (5 times), applying performance, low temperature stability and drying property) can not be exerted in Comparative Example 4 in which a content of the dye is large, Comparative Example 5 in which a content of the dye is small, Comparative Examples 6 and 7 in which a content of the hair dyeing auxiliary agent is small or large, Comparative Examples 8 and 9 in which a content of the lower alcohol is large or small, Comparative Example 10 in which a content of water is small and Comparative Examples 11 and 12 in which a pH of the hair dye is deviated from a range of 2 to 4.
